Game Resources / NES / Shinobi

This game uses the same (but older) engine as Wrath of the Black Manta. Most of the mechanics are same with fewer features or different limits.

Rules

First frame when you get control you can do whatever you want.

Falling from a platform costs 1 frame

Shooting pauses you on ground, you must do it in air

Shooting alters Y speed/Y max height

You can instakill but it takes a lot of frames

Bosses accounts HITs taken, not dmg, therefore the power up is totally useless apart from killing enemies.

Power-ups sucks. You need to avoid "BONUS STAGE".

The white frizbee guys can only hit at the legs if they still weild it... seriously.

Tricks

Jump manipulation with firing

Different from WotBM.

Delaying jump increase with 1 frame: A,B.

Max Y height + 2 = B after 19 frames.

Max Y height + 3 = B after 15 frames.

Max Y height + 4 = B after 9 frame.

Going through walls vertically

You need 4~5 Y speed. Fire before colliding a wall to get a lower Y height, resulting in passing through it.

Get inside wall

Different from WotBM, you need to fire + direction when colliding. This way you are 1px inside the wall. Unfortunately you can't jump from there.

Falling down with 1px/f horizontally

Generally you drop off from platforms with D,D+A which is as slow as in the beginning of the levels. Press D,D,D+A to start falling down with 1px/f.

Damage-boosting

Direction (where you will be thrown) depends on enemy's facing. Every facing results in a "left-side thrown" except if he is facing right. The travel time SHOULD be infinite but you can collide with a wall (for example a ceiling) and you will stop to recieve X pos increases while still unable to take action.

Enemy manipulation

Depends on player X, pressing B and number of objects (6 is the max, document which accounts really because of interesting test results)
